Abstract: Disclosed herein are surgical tool systems and methods of using such to install a fixator in a biological tissue. The systems are capable of accurately measuring torque and rotational velocity and providing real time feedback to a user during surgery.

Abstract: A detection system includes at least one sensor configured to measure a presence of airborne particles and at least one amplifier circuit in communication with the at least one sensor. The amplifier circuit is configured to monitor a charge generated by the at least one sensor over a time interval. The system further includes a controller configured to monitor the charge accumulated in the at least one amplifier circuit from the at least one sensor at the time interval. In response to the charge of the at least one amplifier circuit, the controller detects the presence of the airborne particles.

Abstract: A tactical chemical detector may include a light array comprising a plurality of light sources; a sensor optic comprising a plurality of optic elements, each optic element in optical communication with one of the plurality of light sources; a sensor array comprising a plurality of sensors arranged on a substrate, each sensor in optical communication with one of the plurality of light sources and wherein at least one vent opening extends through the substrate; a power source configured to selectively provide power the light array and the sensor array; and a housing having a first side and a second side and enclosing the light array, the sensor optic, the sensor array, and the power source.

Abstract: A C-arm apparatus. An X-ray imaging system is coupled to a C-arm, including an X-ray source and an image receptor mounted upon opposing locations, respectively on the C-arm. The C-arm is mass balanced about its axis of orbital rotation and is pivotally coupled to an articulating arm assembly supported upon a wheeled support base. The mass balance enables repositioning of the X-ray imaging system between an anterior-posterior view and an orthogonal lateral view with a single, orbital movement of the C-arm which also causes the views to define an imaging isocenter. The C-arm is preferably miniaturized to an approximate diameter of twenty-eight inches with a source-to-image distance of approximately fourteen inches.

Abstract: An apparatus for receiving chemical compounds carried in a high pressure effluent fluid stream from supercritical fluid extraction. The apparatus includes a heated conduit connected to supercritical fluid extraction device through which an effluent stream flows. The exit port of the heated conduit is located within the airspace of a decompression zone which is free of liquid. A liquid solvent chamber is provided in open communication with the downstream end of the decompression zone into which the effluent stream flows for the recovery of chemical compounds therein.
